PICKER-STICK CHECK.

Specification of Letters Patent.

Patented Apr. 16, 1912.

To all 10 7mm it may concern Be 1t known that I, HENRY core, a citizen of the United States, residing at West VVarren, county of Worcester, State of Massachusetts, have invented an Improvement in Picker-Stick Checks, of which the follow ing description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to picker stick checks which are adapted to check the inward movement of the picker stick soas to prevent it from striking against the end of the slot in the lay, and the object of the invention is to provide a simple check of this nature which can be readily applied to any picker stick which operates in conjunction with a rocker foot.

Some embodiments of the invention will first be described and then the novel features thereof will be pointed out in the appended claims.

In the drawings Figure 1 is a view of the rocker, rocker foot and picker stick of a loom showing my improvements applied thereto; Fig. 2 is a similar View showing a slightly different construction from that shown in Fig. 1; Fig. 3 is an end view of the device shown in Fig. 1; Fig. 4 is a section on the line w-em, Fig. 1; Fig. 5 is a View similar to Fig. 3 but showing an arrangement having two checking springs; Fig. 6 is a perspective view of one of the parts of my device.

3 designates a portion of the loom frame, 4 the rock-shaft carrying'the rocker foot 5, and 6 is the picker stick which has the rocker 7 secured to the lower the bolt 8 in usual manner. These parts are such asare commonly found in looms employing a picker stick with the rocker foot construction and form no part of the present invention and may, therefore, be of any suitable or usual construction. In applying my invention to this rocker foot construction 'I secure a spring or other cushion device to the rocker foot and provide an arm extending laterally from the picker stick with which said spring has engagement, so that when the picker stick is moved forward to throw the shuttle across the lay the spring will be put under tension and will act as a cushion device to cushion the inward movem n f th pi k r stick an prevent the let end thereof by.

tier from striking against the end of the slot in the lay. The laterally-extending arm with which the spring has engagement is shown at 9 and it may be secured to the picker stick in a variety of ways without departing from my invention. As herein shown it is made as an integral part of a plate 10 which is secured to the picker stick and which is herein shown as having the shape illustrated in Fig. 6, that is, it is provided with the stem portion 11 which overlies the picker stick and is clamped between the latter and the portion 12 of the rocker foot and is also formed with the downwardly-extending portion 13 which is situated at one side of the picker stick and at the lower end of which the laterally-extending arm 9 is situated. This member 10 can be conveniently formed from a piece of sheet metal bent into the shape illustrated in Fig. 6.

The spring or cushion device is designated Hand it is illustrated as sustained by a pin or'post 15 which is secured to the rocker foot 5 and extends up through the laterallyextending arm 9 and is provided at its upper end with a collar or nut 26. The spring 14 is shown as encircling this post or pin 15 and as confined between the arm 9 and the collar 26. The post or pin maybe secured to the rocker foot 5 in any suitable way. If the device is to be applied to a rocker foot which is equipped with the usual heel strap spring and which is, therefore, provided with the laterally and downwardly-extending bracket 16 for supporting said spring, I propose to secure said pin let to a holder or supporting member 17 which is shaped to be sustained by said bracket 16. The holder shown in Fig. 1' comprises the horizontallyextending body portion which lies alongside of the rocker foot 5 and extends over the top of the bracket 16 and is provided with the downwardly-extending arm 18 which passes in back of the bracket 16 and has an eye or loop 19 at its lower end through which a clamping bolt 20passes, said bolt serving to clamp the arm 18 to the bracket 16. The horizontal body portion 17 is also clamped to the bracket by means of a clamping bolt 21 which extends down through said support and is provided with ahead 22 which engages underneath the bracket 16. The pin or post 15 is secured to this support or h ld r 17 in any Suitable way as by h r ing the end thereof inserted therethrough and by being held in position by the clamping nuts 23. With this construction it will be readily observed that when the picker stick is moved forwardly into the dotted line position in Fig. 1 thereby to throw the shuttle across the lay, the rocking movement of therocker 7 will through the arm 9 0perate to compress the spring 1 1 and the spring will, therefore, act as a check to the movement of the picker stick. As soon as the picking motion ceases its operation, the spring 14 which is under compression will throw the rocker foot backwardly and thus return the picker stick to its initial position ready for the next pick. The spring 14, therefore, not only serves to check the forward motion of the picker stick and prevent the latter from striking against the end of the slot in the shuttle box, but also acts to return the picker stick to its normal position. The tension of the spring 14 can be readily adjusted by means of the adjustable collar 26, as will be readily understood.

In Fig. 2 I have shown a slightly different construction wherein the post or pin 15 is secured directly to a lug or ear 170 formed integral with the rocker foot 5, but in other respects the invention is exactly like that shown in Fig. 1. Fig. 2 shows the way in which my invention might be embodied n a loom if an entirely new rocker foot was to be employed, while Fig. 1 shows the way in Which the invention might be embodied in a loom without discarding the old rocker foot.

In Fig. 5 I have illustrated an embodi ment of the invention wherein two checking springs 14 are employed, one on each side of the picker stick. In this construction I will employaplate 10 which has two portions 13, one on each side of the picker stick, each of which is provided with a laterally-extending arm 9 and the rocker foot will be provided with the two lugs 170, one on each side thereof, each of which carries a post or pin 15, each pin sustaining a checking spring or cushion device 14.

It will be noted that my invention is comparatively simple and can be readily applied to any loom. When the construction shown in Fig. 1 is employed the supporting member 17 may be made more or less resilient if desired so that part of the checkin}: action will be due to the resiliency of said support or said member may be entirely rigid if preferred.

Having fully described my invention,

1. In a picker stick check, the combina' tion with a rocker foot, of a rocker thereon, a picker stick secured to the rocker, a U- .Shaped plate, one arm of which is clamped between the rocker and picker stick and the other arm of which extends downwardly at the side of the picker stick and the end of which is bent laterally and slotted, a ver: tically-disposed pin secured to the rocker foot and extendin'gupwardly through said slot, and a spring sustained by said pin and bearing against the upper side of said arm.

2. In a picker stick check, the combination with a rocker foot, of a rocker thereon, a picker stick secured to the rocker, a plate provided with a stem which is clamped between the picker stick and the rocker foot, and also provided with a downwardly 43xtending' arm, the end of which extends laterally and is situated at the side of the picker stick, and a spring acting on said laterally-extending portion and serving to check the forward movement of the picker stick.

3. In a picker stick check, the combination with a rocker foot having a laterally and downwardly-extending lug, of a rocker thereon, a picker stick secured to the rocker, a laterallykext'ending arm associated with the icker stick, a plate secured to the laterally and downwardly-extending lug, a pin carried by said plate and extending above said arm and having a collar thereon, and a spring carried by the pin and acting at one end against said collar and at the other on the arm to cushion the forward movement of the pisker stick. I V

4. In a pickercheck, the combination with a rocker foot, of a rocker thereon, a picker stick secured to the rocker, a plate clamped between the picker stick and rocker and pro vided with a horizontally arranged slotted portion situated at one side of the picker stick, a pin fixedly secured to the rocker foot and extending vertically through said slot, a collar on the pin, and a spring interposed between the collar and the slotted portion of the plate.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
